recording condition for three angles, 50°, 0°, and −50°, respectively. (B1–B3) Cropped images from corresponding superresolved holograms of 5 μm beads (at z ¼ ∼0.8 mm) measured at illumination angles ...

UCLA researchers have redefined the concept of a microscope by removing the lens to create a system that is small enough to fit in the palm of a hand but powerful enough to create three-dimensional ...

Contact lenses represent one of the single largest categories of medical devices, with more than 31 million contact lens wearers in the United States alone, according to the Association of Contact ...

It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

For centuries diffraction limited the resolution of optical microscopy. The past 50 years have, however, seen one limitation after another buckle under the ingenuity of a host of wide-ranging ...

Conventional light microscopy has been instrumental for the study of cells and microorganisms; fluorescence microscopy has enabled visualization of even smaller cell features by selectively adding ...

Aspheres allow designers to build smaller, lighter and simpler optical systems, and can be found in everyday products. Edwin Diaz provides a back-to-basics guide to the technology. You may not realize ...
